The mod_cluster HTTP Connector", Expand section "22.7. To configure JVM using Fusion Middleware Control, perform the following steps: Using Fusion Middleware Control, add a new configuration section or modify an existing section in formsweb.cfg to enable or disable use of JVM controller for applications. Opens the Confirmation dialog when deleting a configuration section. If a user starts an ordersApp application, and the application executes Java code, the Forms runtime process will route the request to the JVM controller named commonJVM. to help with debugging. Creates a new configuration section. Processing errors might occur if you add classpaths to this field that specify the location of the following items: JAR files for resource providers. The recommended heap size for typical ingestion scenarios should be no less than 4GB and no more than 8GB. However, in 11g, with JVM pooling enabled, Oracle Forms Services uses a shared JVM controller for Oracle Reports requests. The default value of 0 implies no limit. It also works with Forms' ability to call out to Reports. wrapper.java.maxmemory (1.0.0) Sets the maximum amount of memory in megabytes that the JVM is allowed to use. than -client mode, at the expense of slightly longer startup times. Overflow connections from ordersJVM will not connect to hrJVM, only to child JVMs of ordersJVM. Example Microsoft SQL Server Datasource, 13.13.8. The scope of a child JVM is within the context of a JVM controller namespace. Locate the Java configuration file jvm.config.
